Components monitor to hookup to in-car TV
 

Not sure if it exist but what I want is a computer which is able to monitor the g force , percentage of throttle/brake deployed, temperature/pressure of various components....etc and maybe the possibility to record the whole drive and playback at any time. Sort of like the monitor in the new Nissan GT-R, which of the graphics designed by the makers of Gran Turismo.

Most importantly looking for something that has a video output to connect to my exisiting in-car tv.

Any such device exists?
